FLAP-RETAINER FOR PAPER BOXES.

SPECIFICATION forming part of Letters Patent No. 296,510, dated April 8,1884-.

Application filed January 23, 1884. (N0 model.)

To all whom it may concern.-

Be it known that I, JAcoB O. BAUER, acitizen of the United States, and aresident of Philadelphia, Pennsylvania, have invented an Improvement inFlap -Retainers for Paper Boxes; and I do hereby declare the followingto be a full, clear, and exact description of the same.

My invention consists of the combination of the two outer flaps of apaper box with a retainer attached to one of the flaps, and admitting ofbeing moved over the other flap when it has to be secured, and movedback clear of the same when it has to be opened.

In the accompanying drawings, Figure l is a perspective view of one endof a paper box, showing the inner flaps closed and the under side of themovable retainer on one of the outer flaps; Fig. 2, a view showing theinner flaps and one of the outer flaps closed; Fig. 3, a

closed, but not fastened; and Fig. 4-, a view showing the outer flapsclosed and secured by the retainer.

The body A of the box is quadrangular, and as both ends may be alike,one end only is shown in the drawings.

flaps, a a, (shown in Fig. 1,) and two outer flaps. b b, and to eitherof the latter flaps may be adapted the sliding retainer B, whichconsists, preferably, of a strip of thin metal extending across theouter face of the flap, the

There are two inner end portions of the strip being bent against theinner or rear face of the flap. The retainer may consist of a continuousloop of 5 metal or other available material; but no matter how theretainer is constructed it must be such that it can be movedfreely onthe flap to which it is attached. The outer flap b must be of such alength that when folded down a portion of the under flap b carrying theretainer will be exposed, as shownin Fig. 3, prior to fastening theouter flap b, or when the latter has to be opened. When the outer flap bhas to be secured to the flap b, all that is necessary is to move theretainer over the flap b, as shown in Fig. 4, and when thelatter flaphas to be released the retainer must be moved back so as to be clearofthe edge of the said flap, as shown in Fig. 3.

The inner flaps may be dispensed with when the box has to be used forcontaining articles or material which will not be liable to escape fromthe box in the absence of these flaps.

I claim as my invention The combination of the outer flaps, b and b,

of a paper box, with a retainer, B, applied to one flap and beingmovable over and off from the other flap, substantially as described.

In witness whereof I have hereunto set my handin the presence of twosubscribing wit nesses.
